w mROV'ED BACK-E HOOK.

Tha Schedule mfened to in these Letters Patent and making part of theseme. m

To all 'whom 'it may concern.-

Be it known that I, WILLIAM MCKERAHAN, of the city :md county ofAllegheny, and State of Pennsylvania, have invented a certain new anduseful Improvement in Back-Bund Hook for Harness, being a new article ofmanufacture; end I do hereby declare that the iollowing is a full,clear, and exact description thereof', rolex-ence being had to theaccompanying drawings,

and to the lettersotl reference marked thereon.

lhe nature oi' niy'inventon consists in so constructing a hook for thebatck-band of harness, -that it Cau be enst without the necessity ofcoring out, in making the moulds i'or casting it, thereby furnishing anew and cheap article ot' manufacture.

,lo eintble others skilled in the art to make and use my invention, Iwill proceed to describe its construction and operation. A

ln the acmnnpanyiug drawings, which form part of my specificationliigurel is n. ii'ont viewo` my improvement in hooks fnwimck-bands for harness,representing the hook arranged on a section of' a back-band.

Figure 2 is a longitudinal section of' the same, when out through atline y oflig. 1.

vFigure 3 is a longitudinal section of the hook, when disconnectedl'ronl the back-bend.

A4 is a i'rannc oi' the hook. O is the tongue, the point, I), of' whichis curved down, so as to be below the outsidc surface ofthe frame A.

lhe frame A is provided with an opening, B, the form ot' which isclem'ly shown in the accompanying drawings. By making this opening, B,the space un-V der thc tongue O is made by the line of parting iu themould, between the cope' and dra-g of the flask, which terms are wellunderstood by ironnnoulders Through the medium of this opening B, the.space under the tongue C is formed without the necesslty Of Coresbeiugused in formingmoulds for casting the hook, for

these hooks are cast, and then annealed; that is to say, the hooks areknown in commerce as malleableiron hardware for harness.

The bacleband hook is riveted to the back-band P, in the positionrepresented in fig. 1, and when placed on the under strap, girth, orbell -band, it is placedin the position represented by'thc dotted AlinesX iig. l. The links represented by the dotted. lines show the mode ofconnection between the said two parts of the harness. y

The opening O, in the back band If', is for giving room for passing thelink over the curved end D 0f the tongue 0.

The advantage of my improvement consists in the facility and ease ofmoulding the hook, saving the co1ing-process, and making alight andcheap backband hook. 4

Having thus described the nature and construction of my improvement,

What I claim as of my invention, is

A new article of manufacture, viz, a back-band hook,

consisting of frame A, with opening B, and the tongue O, cast to and onthe frame A, as herein described, and

for the purpose set forth.
